Most children qualify for tonsil removal when they’ve had at least seven throat infections in a single year, five per year for two consecutive years, or three per year for three consecutive years. These thresholds, known as the Paradise criteria, are the standard used by ear, nose, and throat specialists across the US and UK. The other major reason is obstructive breathing during sleep caused by enlarged tonsils. Here’s how to know where your child falls.
The Infection Threshold
Tonsillectomy for recurrent infections isn’t based on a single bad winter. The American Academy of Otolaryngology’s clinical practice guideline, updated in 2019 and still the current standard, lays out specific numbers your child’s doctor will look for:
- Seven or more documented throat infections in the past year
- Five or more per year for the past two years
- Three or more per year for the past three years
Each episode should be documented in your child’s medical record and accompanied by at least one of the following: a fever above 101°F, swollen neck glands, pus on the tonsils, or a positive strep test. If your child doesn’t meet these numbers, the guideline strongly recommends watchful waiting rather than surgery.
That recommendation exists for good reason. Research shows that throat infections in children tend to decline over time regardless of whether surgery happens. A systematic review in Pediatrics found that children with mild to moderate infection histories (fewer than three episodes in the prior year) saw only modest benefits from tonsillectomy. In one trial, children who had surgery averaged about 0.56 throat infections per year compared to 0.77 in children who skipped it. That’s a real difference, but a small one, and it comes with the trade-off of surgery and recovery. Many children simply outgrow the pattern of frequent infections on their own.
Breathing Problems During Sleep
Obstructive sleep apnea is now the most common reason children have their tonsils removed, overtaking recurrent infections. When tonsils and adenoids grow large enough to partially or fully block a child’s airway during sleep, the consequences go beyond snoring. Children with sleep-disordered breathing often have daytime sleepiness, behavioral problems, difficulty concentrating in school, and in severe cases, strain on the heart.
Signs to watch for include loud snoring most nights, pauses in breathing during sleep, gasping or choking sounds, mouth breathing, restless sleep, and bedwetting in a child who was previously dry at night. If your pediatrician suspects obstructive sleep apnea, they may refer your child for an overnight sleep study to confirm the diagnosis and measure how severe it is. For children whose obstruction is caused by enlarged tonsils, removal typically resolves the problem.
When Watchful Waiting Makes Sense
If your child gets frequent sore throats but hasn’t hit the Paradise criteria numbers, waiting is not just acceptable, it’s the recommended approach. The guideline authors emphasize that tonsillectomy is not cost-effective and does not provide meaningful improvements in children below those thresholds.
During a watchful waiting period, you and your child’s doctor track infections carefully. Each episode gets documented with symptoms, fever readings, and test results when strep is suspected. This documentation matters because if the pattern continues and eventually meets the criteria, you’ll have the records needed to support a surgical recommendation. Many families find that the frequency of infections drops before that point.
Other Reasons for Removal
Less commonly, tonsillectomy is considered for peritonsillar abscess, a painful pocket of pus that forms beside the tonsil. A single abscess doesn’t automatically lead to surgery in most practice settings, though recurrent abscesses or abscesses combined with a history of frequent tonsillitis may tip the decision.
Some parents of children with strep-triggered neuropsychiatric symptoms (sometimes called PANDAS) ask about tonsillectomy as a treatment. The evidence here is weak. Individual case reports have described improvements, but larger studies involving dozens of patients have not confirmed a benefit. A review in GMS Current Topics in Otorhinolaryngology concluded that tonsillectomy remains a questionable option for this condition, and the positive outcomes in small case reports may be influenced by medications given after surgery rather than the surgery itself.
Age and Safety Considerations
The current clinical practice guideline applies to children ages 1 through 18. There is no strict minimum age cutoff. A study of 190 children under age 3 who had tonsillectomies found a complication rate of about 10.5%, mostly requiring a longer hospital stay rather than a return to the operating room. Only one child in that group, who had pre-existing cerebral palsy, experienced serious complications. The researchers concluded that age alone should not determine whether surgery proceeds.
That said, younger children and those with severe obstructive sleep apnea are monitored more closely after surgery, often staying overnight in the hospital rather than going home the same day. Children with obesity or certain facial structure differences also receive extra precautions.
What Surgery and Recovery Look Like
Tonsillectomy is performed under general anesthesia and typically takes 20 to 45 minutes. Most children go home the same day, though younger children and those with severe sleep apnea may stay overnight for monitoring.
Recovery is rougher than many parents expect. Pain peaks around days 3 to 4 after surgery and can persist as a sore throat, neck ache, or ear pain for two to three full weeks. Ear pain is particularly common and doesn’t mean anything is wrong with the ears; it’s referred pain from the healing throat. The standard pain management approach combines acetaminophen given on a regular schedule with ibuprofen as needed. Ibuprofen was once avoided over bleeding concerns, but current guidelines support its use after tonsillectomy. Opioid pain relievers are reserved for children over 5 without severe sleep apnea, and used cautiously.
Plan for your child to miss at least seven days of school or daycare, and arrange your own schedule accordingly. Some children need longer. Your child should avoid hard, scratchy, or spicy foods during recovery and stick to soft, cool foods and plenty of fluids. Dehydration from not drinking enough is one of the most common reasons children end up back at the doctor after surgery.
Bleeding Risk After Surgery
Post-operative bleeding is the complication parents worry about most. It’s relatively uncommon but does happen. In a study of 5,000 pediatric tonsillectomies, 1.2% of children were readmitted for bleeding. Of those, about a third needed a return trip to the operating room to stop the bleeding, while the rest were managed with observation or minor interventions. Other studies have reported secondary bleeding rates (bleeding that occurs after the first 24 hours, often between days 5 and 10) as high as 3.4%.
If you see bright red blood from your child’s mouth or nose during the recovery period, or if your child is spitting blood repeatedly, that warrants an immediate trip to the emergency room. Small streaks of blood in saliva or a pinkish tinge when your child spits are more common and usually not an emergency, but any concern is worth a call to the surgeon’s office.
